It's no secret that raising a family takes balls. But this study seems to show that, at least in regards to how active a role a man will
take in his child's upbringing, size means more than we realized.

Published in the Proceedings of the National Academy of Sciences, proud bearers of the situationally-apt acronym PNAS, the study
claims that men with larger testicles may be less likely to man up and engage in activities such as changing diapers and warming up bottles. This lack of attentiveness the researchers attribute to the higher levels of testosterone
brewed thanks to the larger cauldrons in which to distill the hormone, and this naturally leads to a stronger inclination to mate more and worry less about the resulting offspring. This isn't to say that dudes with more dangle definitely won't get their dad on, but they may have less of a natural nurturing inclination.

While we're not insinuating that all the daddy bloggerssmugly shopping for formula
with Cosbysweaters on are lacking in cojones, it is a
fairly well-known fact of science that the larger the balls, the more they want
to play the game.

But before you brag about your sag,
or use it to make excuses when the baby monitor goes code red at 3 a.m., let's
all take a moment to ponder the bush cricket,
whose nuggets account for 18 percent of its body mass. That's roughly the human
equivalent of 11 pounds. Who's bragging now?
